Web Services programming tips and tricks, Part 4: Bring J2EE and .NET together in a business process using BPEL and WebSphere Business Integration Server Foundation

27 May 2005 04:00:00 +0000

Investigate a typical business integration scenario between J2EE (Java(TM) 2 Enterprise Environment) and Microsoft(R) .NET and learn how to build and run a BPEL (Business Process Execution Language) business process on IBM(R) WebSphere(R) Business Integration Server Foundation. In the first three parts of this series about improving interoperability between J2EE technology and .NET, Wangming Ye analyzed the common challenges facing a Web services integration between J2EE and .NET, and offered best practices. This tip focuses on the delicate design of XML schemas that Web services programmers often overlook. The objective is to show how to avert common Web service interoperability challenges between .NET and J2EE, such as nested complex-type arrays, date and time values, and namespace issues, through a top-down approach (WSDL (Web Services Description Language) implementations).

Web services programming tips and tricks: Handle namespaces in SOAP messages you create by hand

03 May 2005 04:00:00 +0000

Gain a thorough understanding of how WSDL maps to SOAP. Under normal circumstances, you don't have to worry about namespaces in the SOAP message. But there are times when you must. This tip prepares you for those times when you have to create your SOAP message by hand and deal with namespace issues without the help of a tool.

Web services programming tips and tricks: Develop a UDDI Java application for Web services registered within a UDDI registry

27 Jul 2004 04:00:00 +0000

This tip establishes the case for using Universal Description, Discovery, and Integration (UDDI) to register Web services for application-level consumption. It provides detailed code samples and an extension API based on the Universal Description, Discovery, and Integration for Java (UDDI4J) API that will enable you to begin utilizing UDDI for your own development purposes.

30 Nov 2006 05:00:00 +0000

JAX-WS 2.0, the successor to JAX-RPC 1.1, has evolved its data mapping methods by using JAXB (the Java Architecture for XML Binding), a JCP-defined technology. This second tip in a series compares the data mappings of these two Web services specifications.

Web services hints and tips: JAX-RPC versus JAX-WS, Part 3

13 Jun 2007 04:00:00 +0000

This third part of the series about Java(TM) API for XML-based RPC (JAX-RPC) 1.1 and Java API for XML Web Services (JAX-WS) 2.0 compares the mapping of Web Services Description Language (WSDL) to a service endpoint interface (SEI). The concept of an SEI was first introduced in JAX-RPC 1.0 and has been maintained in JAX-WS 2.0, with some additions. This tip walks you through the major differences.
